Adhesivo Carbotec Impregnante

Carbotec impregnante adhesive is a resin which, due to its impregnation and thixotropy allows the adherence of the carbotec tissue on concrete elements, reinforced concrete or brickwork.

Additional information

Features and applications

  • Highly thixotropic, no dripping
  • The adherence to the concrete exceeds the material cohesion.
  • Curing without retraction.
  • High resistance.
  • Once the curing process is over it will be resistant to bases, dissolved acids, mineral and aliphatic oils and saline solutions.
  • Resistant to temperature changes within -30ºC to 80ºC in dry exposition, and superior to +40ºC in humid exposition.


  • In order to ensure an optimum distribution when having roughness in excess, it should be filled and levelled with adequate materials.
  • The substrate must be dry, clean and free from dust in order to apply adhesivo carbotec impregnante. 
  • The adherence of the ready substrate should be verified by adhesion tests in random areas. The concrete should have 1,0 N/mm2 minimum adhesion.

Instructions for use

  • Pour component A and B in a clean container and mix them properly for 3 minutes with a low velocity mixer until getting a homogeneous mixture.
  • Mix everything carefully and make sure  that the hardener is also uniformly distributed.
  • The temperature of both the components should be 15ºC-20ºC when mixing; higher temperatures may reduce the open time.
  • Protect the resin against humidity for 6 -8 hours after the application. Any contact with humidity will turn the surface white and will loose its adherence. If the product is used as a
  • Apply the adhesivo carbotec impregnante with a roll (300g/m2)in continuous thickness and with a primer, preventive measures should be increased. The width should tower over 5 cm more than the carbotec tissue.
  • Pressure the carbon fibre mesh against the adhesivo carbotec impregnante with a special roll: solid rubber roll that allows the adhesive penetration through the tissue's fibre.
  • Always work from the from to the back following the carbon fibres direction. Start in one of the corners and work towards the other; or start in the middle and move towards both the sides; this will eliminate all the air that may be trapped.

Cautions and recommendations

  • Consult our Technical Department for any application that might not be specified in this Technical data sheet.
  • In order to clean the tools, we suggest cleaning them with a solvent such as ethylic alcohol, toluene before it gets hard.
  • For additional information regarding the safe handling, transport, storage and use of the product please refer to the label and the updated version of the product Safety data sheet.
